Brief bio: I am interested in understanding plant adaptation to abiotic and biotic stresses in cereals. The study of stress responses in cereals in the context of reproductive development has the potential to greatly improve our understanding on how to enhance their tolerance under diverse stress conditions. For the last 3 years, I have been exploring the impact of heat stress on pollen development. In our manuscript, we showed how short moderate heat stress during the highly susceptible tetrad stage especially affects basic metabolic pathways and thus generates germination defective pollen, ultimately leading to severe yield losses in maize.

作者简介：目前我的研究项目主要试图了解农作物对非生物和生物胁迫的适应性，尤其是生殖发育阶段对逆境的应激反应。这项研究很大程度上能帮助我们理解作物是如何在不同逆境下增强其耐受性的。在过去的3年里，我一直在探究热胁迫对玉米花粉发育的影响。在这篇文章中，我们展示了在玉米花粉对环境变化极其敏感的四分体时期，短期的热胁迫是如何影响基础代谢过程进而导致成熟花粉萌发异常，最后导致结实率严重下降。
